6 Claims.

This invention relates to winding spools and more particularly to an improved spool and spindle assembly for use in winding strand material.

The present invention is particularly adapted pulley aflixed to the spindle adjacent one of thespool ends. It is obvious, of course, that the connection between spool and spindle should be sufficiently tight to prevent vibration and slippage during operation, and should likewise be of such a nature that spool and spindle may be easily and quickly separated, so that a filled spool may be replaced with an empty one and the winding operation continued without unnecessary delay.

An object of the invention, therefore, is the provision of an improved winding device, wherein a tight connection is maintained between the spool and spindle.

Another object is the provision of an improved spool and spindle assembly of simple construction whereby a filled spool may be quickly and easily removed and replaced with an empty spool.

A further object is the provision of an improved spool and spindle wherein the spindle is held in frictional engagement with the spool.

Other objects and advantages will appear from a consideration of the following specification when read in conjunction with the annexed drawing wherein Figure 1 is an elevation, partially in section, of

, my improved spool and spindle assembly, showing the spindle partly inserted in the spool,

Figure 2 is a view similar to Figure 1 showing the spindle in operative engagement with 'the spool, and showing the driving arrangement,

Figure 3 is a section taken along the line 33 of Figure 1,

Figure 4 is an elevation, partially in section, showing a modified form of spool and spindle assembly according to my invention, and

utilized in practicing the present invention comprises a cylindrical body portion 6 having heads 2 and 3 amxed to the ends thereof. The spool is provided with a central bore 4 extending longitudinally thereof adapted to receive a spindle 5.which. when fully inserted therein, projects from the spool at both ends.

Afllxed to spindle 5 near one end thereof is a pulley 6 preferably made of wood and having a beveled face 1. Pulley 8 is provided for a portion of its length with an outer layer of cork or the like a to provide a suitable contact surface for the driving mechanism by which the pulley is rotated. Likewise affixed to spindle 5 adjacent Figure 5 shows the same modification in opthe beveled face of pulley 6 is a resilient metal strip or spring key 9 adapted for insertion in an annular recess Ill in spool head 2 concentric with central bore 4. Recess no is flared so that its inner diameter is greater than the outer diameter thereof, and its rear wall is concave and extends into the body of the spool. Also concentric with bore is is a counterbore H of lesser diameter than the recess, and adapted to receive a hub I2 affixed to spindle 5 adjacent pulley 5. The length of spring key' 9 is slightly greater than the inner diameter of annular recess ill, but is bent slightly in the direction of the spool so that, upon insertion of spindle 5 in bore l spring key 9 will'pass through the mouth of the said recess. The side I of pulley G-is beveled to conform to the shape of the concave rear wall or recess l0, and upon exerting pressure upon the spindle end adjacent the pulley, spring key 9 will spread until the edges thereof contact the inner periphery of recess l0 and its face will contact the concave rear wall of the recess. Simultaneously hub I2 is inserted in counterbore II.

It is obvious, of course, that counterbore H and tate placement and removal of spools. Pulley 6 is rotated by contact with a wheel l5 mounted on a-shaft i6 and driven from any suitable source of power, not shown.

In the modification shown in Figures 4 and 5 the function of recess l0, shown in Figures 1 and 2, is served by an annular concave dish-like memher I! affixed to head l8 of a spool I9 by means of screws or bolts 20. Spool I9 is provided with a central bore 2| adapted to receive a spindle 22, having affixed adjacent one end thereof a pulley 23 and a spring key 24. The spindle, pulley and spring key assembly shown in Figures 4 and 5 is similar in every respect to that shown in Figures 1 and 2 except that counterbore II and hub I! are eliminated.

It should be understood that a slight pressure exerted upon the end of the spindle adjacent the pulley will force the spring key into locked position in annular recess III or concave member l1, and that a slight pressure against the opposite end of the spindle will be sumcient' to sever the connection between the spool and spindle and permit easy replacement of the spool.

It should be further understood that modifications may be made in the present invention without departing from the spirit thereof. Therefore, my invention should be limited only by the scope of the appended claims.

What is claimed is:

.1. A collecting device for strand material comprising a spool, an annular receiving means having a concave inner wall associated with one end only, of said spool concentric with the axis thereof, a spindle, and a radially projecting metallic spring key aflixed to said spindle, said spring key being normally urged in the axial direction of the spool and arranged for frictional engagement with the inner wall of said annular receiving means.

2. A collecting device for strand material comprising a spool, a spindle extending therethrough, a driven pulley affixed to the spindle exteriorly of the spool, an annular receptacle associated with one end of said spool and concentric with said spindle, and a radially projecting, metallic spring key afllxed to said spindle, said spring key being normally urged in the axial direction of the spool and arranged for frictional locking engagement with a wall or said annular receptacle.

- 3. A collecting device for strand material comprising a spool, a spindle extending therethrough,

a driven pulley afllxed to the spindle exteriorly of the spool, a flared annular recess concentric with said spindle and having a concave rear wall in one end of said spool, and a metallic spring key afllxed to and extending radially from said spindle adjacent the inner end of said pulley, said spring key being normally urged in the axial direction of the spool and arranged for frictional locking engagement with the walls of the annular recess.

4. A collecting device for strand material comprising a spool, a spindle extending therethrough, a driven pulley affixed to the spindle exteriorly of the spool, a flared annular receptacle aflixed to one end of said spool concentric with said spindle and having a concave rear wall, and a metallic spring key aflixed to and extending radially from said spindle adjacent the inner end of said pulley, said spring key being normally biased in the axial direction of the spool and arranged for frictional locking engagement with the walls of the annular receptacle.

5. A collecting device for strand material comprising a spool having a central bore extending longitudinally thereof,-a, spindle extending therethrough, a driven pulley affixed to the spindle exteriorly of the spool, one end of said spool being provided with a tapering annular receptacle concentric with said bore, and a beveled, metallic spring key affixed to and extending radially from said spindle adjacent the inner end of said pulley, said spring key being normally biased in the axial direction of the spool and arranged for frictional engagement with the walls of the tapered receptacle. Y

6. A collecting device for strand material com--' prising a spool having a central bore extending longitudinally thereof, a spindle extending therethrough, a driven pulley aflixed to the spindle exteriorly of the spool, bearings for the spindle adjacent the remote ends of the pulley and spool, one end of said spool being provided with a tapering annular recess concentric with said bore and terminating in a counterbore, a metallic spring key aflixed to-and extending radially from said spindle adjacent the inner end of said pulley and a hub mounted on the spindle adjacent said spring key, said spring key being normally biased in the axial direction of the spool and arranged for frictional engagement with the walls of the tapered recess when the spindle with the spool thereon is mounted in said bearings, said hub being retained in said counterbore.
